Chrysanthemum plant named ‘Moza SI 01’

ABSTRACT

A new and distinct Chrysanthemum plant variety characterized by a pink/white color ray florets, consistent flowering response to short days, blooming consistently after 49 days of short day length, small foliage, long lasting blooms, and consistent natural season flowering habit during late September.

Latin name of the genus and species of the plant claimed: Chrysanthemum morifolium.

Variety denomination: ‘Moza SI 01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, and herein after referred to by the cultivar name ‘Moza SI 01.’

This new cultivar originated from hybridization of a female parent Chrysanthemum cultivar MZ 215-01 (unpatented in the United States, and undistributed commercially) and a male parent Chrysanthemum cultivar MZ 257-01 (unpatented in the United States, and undistributed commercially). The new cultivar was discovered by the inventor in November 1998.

Asexual reproduction of the new cultivar by apical tip cutting and meristem tissue culture was performed in Oxnard, Calif. and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Moza SI 01’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Moza SI 01.’ These characteristics in combination distinguish ‘Moza SI 01’ as a new and distinct Chrysanthemum:

1. Pink/white color ray florets;

2. Consistent flowering response to short days, blooming consistently after 49 days of short day length;

3. Small foliage;

4. Long lasting blooms; and

5. Consistent natural season flowering habit during late September.

Plants of the new cultivar are similar to plants of the female parent cultivar in most horticultural characteristics, however plants of the new cultivar differed from plants of the female parent cultivar in the following characteristics:

1. The new cultivar has different color ray florets;

2. The new cultivar has a smaller diameter bloom;

3. The new cultivar is shorter; and

4. The new cultivar has a shorter internode length.

Plants of the new cultivar are similar to plants of the male parent cultivar in most horticultural characteristics, however plants of the new cultivar differed from plants of the male parent cultivar in the following characteristics:

1. The new cultivar is taller;

2. The new cultivar has a larger bloom diameter; and

3. The new cultivar naturally blooms 2 weeks later.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in a commercial filed on Oxnard, Calif. in the month of September 2000. The plant described is approximately 80 days old, and was grown from a rooted cutting given one pinch after 10 days from planting. There was no spray or disbud treatment given. The growing conditions range from 60° to 65° F. at night to 70° to 85° during the day. Measurements and numerical values represent averages of typical flowering types.

Botanical classification: Chrysanthemum morifolium cultivar ‘Moza SI 01’.

Commercial classification: Garden-type Chrysanthemum.

Parentage: Hybridization of a female parent Chrysanthemum cultivar (unpatented in the United States) and a male parent Chrysanthemum cultivar (unpatented in the United States).

Commercial comparison: Comparison variety “Roadrunner” U.S. Plant Pat. No. 11,298, the most similar multi-color ray floret variety. The new variety differs from Roadrunner in having a later natural season bloom time, many more inflorescences per flowering stem, smaller diameter inflorescence, pink/white ray florets as opposed to red/yellow ray florets, and more disc florets than Roadrunner.
